Abstract: 1284093 Hovercraft A M LIPPISCH 24 Oct 1969 [25 Oct 1968] 52161/69 Heading B7K The underside of the body 10 of a hovercraft operating over water is shaped at the bow so as to form a cavity 11 open towards the front, so that in motion a supporting air cushion is generated therein by ram-air effect. To the sides of the body 10 are attached airfoils 14 and at the rear are side fins 13 supporting an elevator 15. Engine 16 propels the craft by means of a water-screw (19, Fig. 2, not shown) and steering is effected by means of a rudder (18). The trailing and outboard edges of the airfoils 14 may be at the same general level as the bottom of the hull of the craft so that in motion they also will produce air cushions by ram-air effect, as well as producing aerodynamic lift. As speed increases this lift will increase, tending to raise the craft; this will decrease the lift produced by the air-cushions beneath the airfoils 14 and in the cavity 11.
